Leaching of metals from reclaimed asphalt and their effect on living organisms

Popis výsledku v původním jazyce

The article describes leaching of metals from the reclaimed asphalt (RA) repository under real conditions and laboratory leaching tests of the same material. Ecotoxicity tests have also been carried out to determine the impact of seeping water and RA material leachate on living organisms. The specific sampler was used to collect seeping water samples. Sampling was conducted in two campaigns. Seeping water collected during the first sampling campaign was typical with very high concentrations of Zn and high concentrations of Sb, Ni and Ba. The composition of the sample taken in the second campaign was different. The concentration of Zn was two orders of magnitude lower, Ba concentrations were two times lower, Cr concentrations were nearly four times lower. On the contrary, concentrations of Mn, Ni and Sb were significantly higher in the second sample. Only the concentrations of Cu, Mo, Pb, V and Cd were roughly similar in both samples. The chemical composition of RA material and rainfall were monitored as well. The RA material from the repository contained high concentrations of some metals, especially Mn, Cr, Ba and V. The results of the experiment showed that laboratory material leachate contained very low concentrations of metals while seeping waters contained the same metals in much higher concentrations. Effect of seeping water and RA material leachate on test organisms was small and limit values defined in Czech Regulation no. 387/2016 Coll. for all measured parameters were observed.
